Abstract: Objective: To investigate the cognition and behavior of patients’ medication compliance among hemodialysis nurses. Methods: Totally 233 hemodialysis nurses from 10 general tertiary Grade A hospitals were investigated by general information questionnaire and hemodialysis nurses' cognitive and behavioral questionnaire on patients' medication compliance. Results: Hemodialysis nurses had good cognition of medication compliance and poor behavior. Currently, only 52.8% of hemodialysis nurses asked each patient about their medication. The results of univariate analysis showed that there were significant differences in the cognitive scores of different titles of hemodialysis nurses in the occurrence of drug noncompliance and the patients prone to drug noncompliance (P<0.05). There were statistically significant differences in cognitive scores of hemodialysis nurses with different ages in improving medication compliance disorder (P<0.05). There were statistically significant differences in cognitive scores between hemodialysis nurses with different working years and nurses with or without blood purification specialty in improving medication compliance (P<0.05). Conclusion:There are still some deficiencies in the cognition and behavior of hemodialysis nurses to patients' medication compliance. Nursing managers should carry out hemodialysis nurses training to improve patients' medication compliance. Nurses should pay more attention to patients' medication compliance, and explore evaluation tools for clinical application of medication compliance.
